our project was about making house with 4 rooms and each room should have a separate light .we made a home with 4 rooms then we made circuits to be sure their going to work . we tried some blogs for help us for that. then we made a series circuit consisting and switch with 2 lights bulb ,one parallel circuit one complex and one for us and we choose to use the first one again .we used different light bulbs for our home and then we put furniture there.

PROJECT QUESTIONS

You have three lights bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in series by unscrewing one light bulb. Support your answer.

-the wire can send the –charge to light from battery and then get the + charge from anther side of light then the another side came back to battery with + charge and then the light will be turn on .if we want we could add a switch too.

You have three light bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in parallel by unscrewing one light bulb.

-they will connect to each other because the law is saying that when we put the light and battery and wire and switch they could connect and the lamp getting on.

You have three light bulbs. Two are connected in parallel. This parallel combination is connected in series with the third light bulb. Describe the relative intensity of each bulb. Support your answer.

-when they are parallel means they could connect one more light from another side

In question number three, describe the relative intensities of the two remaining lit bulbs if one of the bulbs in parallel was unscrewed. Support your answer.

I have been hired by my family to outline three option for your current house to become more energy efficient.

I live in a apartment and we have a 3 big window and one big balcony with glass door we have 3 bedrooms and 2 bathrooms ,our home Is really cold in winter and really hot in summer and I have 3 option to save more energy in home.

DISCOVER

we have a good view in home and when it is a summer the sun is right beside us and our home always getting warm and we need use the air conditioner . I am thinking about if we change our windows glasses to the tinted glasses and that can help to the house don’t get warm in summer and we can save more energy when the home is not really hot.

the next thing is opposite. we are living in level30 and it is really cold in winter because I believe that when our home is in high it is colder than the town houses. or probably that is because we have a big windows and that is the reason our home getting really cold . it would be a bad things because we pay for the heater and we use it in all the winter but our home still cold I think if we change the glasses to thermal insulation glass in winter that can help us to have a warm home in winter.

our home has a big luster and some small light in somewhere on ceiling. but some places in home does not have enough light for study or stay there and we should use the little light night and that is bad because some places has too much light and some does not have enough and I think if we use the smaller luster and put the lights to some places that they does not have enough light . if we do that we do not need any of the small lights there.

DREAM

my dream is the new technology would happened that we gave a degree of the weather and that could open the windows or turn on the heater or air conditioner to home has a same degree always .

we finally did this project done. The importance of our project is a cooperation between us. Our project was about the effect of deforestation on birds life and why the birds are important.we gave the audience good information about what we did and how this project get done we talked about the birds and why they are important actually I can’t say more .if you want give some information or this subject make you interested you should watch it. and of I had a more time I liked to add my voice little bit and maybe add some birds voice in a first of film.our audience are riverside student.we chose this subject for our project because the birds living is important for the humans life and some peoples do not knowthst the birds are important about the other animals life too.

Americans certainly do use a lot of water. According to CBS News, the average American uses 150 gallons of water per day, while residents of the U.K. only use 40 gallons per day and residents of China use just 22 gallons per day.According to a new report released by the Natural Resources Defense Council, more than one-third of all counties in the lower 48 states will likely be facing very serious water shortages by 2050. That is just 38 years away. As water becomes more scarce and as big global corporations lock up available supplies, the price of water is almost certainly going to skyrocket. This will put even more economic pressure on average Americans.

Another popular opinion is that the amount of available freshwater is decreasing because of climate change. Climate change has caused receding glaciers, reduced stream and river flow, and shrinking lakes and ponds. Many aquifers have been over-pumped and are not recharging quickly. Although the total fresh Of water sweet don’t use not,but we have to continue to the water passion also needs.

water supply is not used up, much has become polluted, salted, unsuitable or otherwise unavailable for drinking, industry and agriculture. To avoid a global water crisis, farmers will have to strive to increase productivity to meet growing demands for food, while industry and cities find ways to use water more efficiently.

Although a mere 0.014% of all water on Earth is both fresh and easily accessible (of the remaining water, 97% is saline and a little less than 3% is hard to access), technically, there is a sufficient amount of freshwater on a global scale, for humanity to get by. However, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades, humanity is facing a water crisis, with demand expected to outstrip supply by 40% in 2030, if current trends continue.

This world will not end by a world war, an asteroid, a virus, a natural disaster, a specificman-made disaster, or any of the other typical events people imagine. And it’s not that some (or even all) of these things won’t occur between now and the time of the End, and be extremely devastating to life on the planet, even significantly reducing the Earth’s population by their cumulative effects. and we know we will die.and for finish the water of the earth.and the humans cant do anything.

what questions did you need to research in order to research your topic?

the important question i have been researching about is water shortages.and do people have a way to prevent water shortages? but the answer i did not get was,why do not they find a way to convert water to food.

what new of familiar digital tools did you try to use as you worked through this project?

i helped the school library site but google and vicipedia helped me a lot too.

what was the process you used to investigate the topic?

I’m always afraid of dying and I’m scared of a lot of water. In my country there is a watering day that he has been dry for a long time. My country is very warm. In return, Canada is. But the problem is that water scarcity is a serious problem. Because we have water, but there is little water or sweet water.

how did you verify and cite the information you found?

I did not have much to do with the library site, and I received more answers than Wikipedia. Under Wikipedia, the entire text can be translated into another language, and I could more easily figure out what I’m writing and what I’m answering. Of course, most of my answers came from Google.

how did the process of completing this challenge go?what could you have done better?

This project helped me get started with the elementary science of science at the beginning of the science class. I find the biggest question I have, which has its own hardship. The greatest of them was that this was my first project in English.
